WALL FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent N0. 771,816, dated October1 1, 1904.

Application filed December 4, 1903. Serial No. 183,841. (No model.)

To all whom it may concern.-

Be itknown that LJOHN ALBERT FERGUSON, a citizen of the United States,residing at Denver, in the county of Denver and State of U010- rado,haveinvented certain new and useful Improvements in Walls for Buildings; andI do hereby declare the following to be a full, clear,

and exact description of the invention, such as The objects of myinvention are to provide a building-wall which will be solid andsubstantial, one that can be very easily constructed, also one that willprevent the penetration of moisture, as it is provided withair-chambers.

Referring to the accompanying drawings, Figure 1 is a perspective viewof the block used in my wall. Fig. 2 is a view of a course of blocks.Fig. 3 is a perspective view of a section of wall constructed of myblocks.

1 refer more fully to the drawings by designating the main portion ofthe blocks with the letter A. This main portion is provided withangularly-disposed flanges or projections at each end which aredesignated by A and A A short extension A projects from the centralportion of the blocks, the face width of which is preferably double'that of the face width of the ends of the flanges indicated by A and Awhich will be made manifest by consulting Fig. 2 of the drawings.

I construct my wall of two courses of the blocks as described, and shownin the drawings. The courses placed upon the first ones are so laid thatthey will break joints, as shown in Fig. 3 of the drawings. 7 Thisprovision is of utility, as it provides a thoroughly effective bond forthe wall. The blocks may be laid in any suitable mortar or cement andare preferably arranged with the terminal proj ections of the blocks onone side of the wall facing the intermediate extensions of the blocks onthe opposite side of the wall, as shown.

I am aware that blocks of similar construction have already beenpatented; but blocks of the specific construction by means of which thebond is secured in the manner shown and described, by using blocks whichare all constructed alike, are new.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. A wall composed of a plurality of blocks each havingangularly-disposed terminal projections and an intermediate extension ofless length than said projections but of greater face width, said blocksbeing laid side by side and arranged in superposed courses with theterminal projections of the blocks on one side of the wall facing theintermediate extensions of the blocks on the opposite side of said wall.

2. Awall composed of a plurality of blocks each comprising a bodyportion having terminal projections arranged at right angles thereto anda centrally-disposed extension of less length than said projections butof greater face width, said blocks being laid side by side and arrangedin superposed courses with the terminal projections of the blocks on oneside of the wall facing the intermediate extensions of the blocks on theopposite side'of said wall.

3. The herein-described building-block comprising the body portionprovided at each end with a laterally-extending web and between its endswith a centrally-disposed web, the end webs being longer than thecentrally-disposed web, and the latter being thicker than the end webs,substantially as described.

In testimony whereof I hereunto aflix my signature in presence of twowitnesses.

JOHN ALBERT FERGUSON.
